Three-dimensional inverse synthetic aperture radar

This chapter introduces the development of a method for 3D reconstruction of moving targets. This method is based on the use of a dual interferometric ISAR (InISAR) system. The interferometric phases measured from two orthogonal baselines are used to jointly estimate the target’s effective rotation vector and the heights of the scattering centres with respect to the image plane. The algorithms are tested on a variety of simulated and real datasets Chapter Contents: • 2.1 Introduction • 2.2 Algorithm description • 2.2.1 Multichannel ISAR signal model • 2.2.2 System geometry • 2.2.3 Received signal modelling • 2.2.4 Multichannel CLEAN algorithm • 2.2.5 3D reconstruction processing • 2.3 Performance analysis • 2.3.1 Scatterers realignment • 2.3.2 Soft assignment • 2.3.3 Performance indicators • 2.4 Results • 2.4.1 Simulated results • 2.4.2 Experimental results • 2.5 Conclusion • References.
